Patented May 1, 1906.

which the following description, in connec- "tion with the accompanyingdrawings, 1s a specification, like characters on the drawingsrepresenting like parts.

k This invention relates more particularly to so-ealled feeler-loomsprovided with auto matic mechanism for replenishing the runninfillingp'rior to complete exhaustion thereo In such looms the end of theold fillingextends "from the cioth :70 the sliuttle contain ing thefilling-supply to be abandoned at the time filling change is to beeffected.

'and t --Means have been devised to art or sever such thread adjacentshutt e and there afterto art it adjacent the edge of the-cloth, andiinnited States Patent to Draper, No. 683,423, dated September 24, 1901mechanism is shown for not only so parting the thread, but also to catchor hold the severed piece and prevent it from being woven into thecloth.

The parting adjacent the cloth is effected by a thread-cutting temple,and the thread is clamped and arted adjacent the shuttle by separatemechanism, after which the latter is moved toward the cloth to slightlyslacken the clamped end of thread as it is brought into ran e of thethread-cutting templc to avoid breifiiing the thread.

My present invention isI-in some of its general features ver similar tothe structure shown and described inthe patent referred to; but I havedevised improved means for more securely and eiiectuall y clamping thethread, so that there can be no tendency for it to 1pull out from theclamp prematurely,

ereby I insure the parting by the temple thread-cutter and prevent anyliability of the filling end being woven ito the selvage of the cloth.

' The novel features of my invention will be fully described inthesubjoined specification and particularly pointed out in the followingclaims( I have shown my invention as applied to a loom wherein therunning-shuttle 18 provided automatically with a fresh supply of fillinat the proper time; but it will be manifest t at it is equallyapplicable to a loom provided with shuttle-changing mechanism.

Figure 1 is a transverse sectional view of a portion 'of a loom providedwith automatic filling-replenishing mechanism, showing a portion of suchmechanism, one embodiment of my invention being illustrated inconnection therewith and in normal inoperative position. Fi 2 is a topplan View of a portion of the mec anism shown in Fig. 1 confinedprincipally to the parting and clamping devices. Flg. 3 is an inner sideview, enlarged, of the thread-parter and thread-clamp after the threadhas been clamped and arted. Fig. 4 is a top plan view thereof; an Fig. 5is a transverse section on the line 5-5, Fig. 3,

looking toward the right and showing clearly the manner in which thethread is'clamped.

As in the patent referred to, the parter and clamp are herein shown soconstructed and arranged that the will be in position to act beingmounted separate y and being stationary as a whole.

Referring to Fig. 1, the lay A the feeder F to hold the filling suppliesor carriers b, the transferrer f, fulcrumed at f, the controllingrock-shaft d, turned in the direction of arrow when the replenishingmechanism is to be operated, the notched dogm operatively connected withthe depending end of the transferrer, and the bunter C on the lay to attimes cooperate with the dog may be and are all as in said patent. So,too, the shuttle-feelerrY, having its hub y, Fig. 2, mounted on the studa to rock thereon and also tornove laterally thereon, (the means toeffect such lateral movement forming no part of my invention,) the stud1 on the shuttle upon the filling w en the shuttle is properly,

feeler Y, having an attached finger n to control'the rotative movementof the dog m on its support, the arm (2", fast on rock-shaft d V malinoperative position, as illustrated in j 15, interposed between thehead of the screwt v .M.

Fig. 1, may be and are as in the patent hereinbefore referred to.

The upper extremity of the feeler Y notched at 1, Figs. 1 and 3, toreceive the tilling-thread when the feeler is moved into operativeposition adjacent the mouth of the replenishing shuttle-box B Fig. l,and a fixed cutting-blade 2 is secured to the feelcr at the lower edgeof the notch 1.

On the headed screw-stud 3as a fulcrum is mounted the member 4, which isat once a cutting-blade and a clamping-jaw, its lower edge 5 cooperatingwith the blade 2 to part the filling-thread at the proper time, (seeFig. 5,) said member 4'resting against the flat face of the 'feeler andhaving at its front end a depending heel 6, Fig. 3.

A fixed or stationary member 7 of the thread-clamp is arranged tocooperate with the adjacent face of the combined blade and clamp memberor jaw t, the member 7 having a notched end 8 adjacent the feeler-notch1, but with its lower edge 9 above the upper edge of the fixed blade 2.This tixed member 7 is held in place by the screw-stud 3 and by a pinit), fixed in the fecler and passed through the member 7, the pinextending loosely through a slot 1 l in the movable member 4. (Seedotted ines Fig. 3.)

By reference to Fig. 4 it will be seen that the member4 iscut away orreduced in thickness at 12 to accommodate the lixed member or jaw 7 ofthe tlnead-clamp. Adjacentthe outer face of the member 7 .l haveprovided a second clamping member .15 fulcrumed on the screw-stud 3 andlixedly.attached, as by rivets H, to the thick ftnward end of the member4 to move in unison therewith and so placed. that it moves up and downagainst the contiguous face of the lixed clamping-jaw 7. The member 13is also slotted to correspond with the slot 11 for the pin i(),and inFigs. 4 and 5 the relativepositions of the. members 4, 7, and 13 areclearlyshown. A spring-washer stud 3 and the adjacent face of the member13 of the thread-clamp, holds the said member yieldingly pressed againstthe fixed jaw 7 and presses the latter against the blade-jaw 4., in turnholding the latter against the inner face of the feeler. Atlllttl(l-[')ztli.0l eomprising the fixed blade 2 and the movable blade4, is thus provided with a double-acting threadclamp comprising themovable jaws 4 and I3 and the interposed fixed jaw 7, both parter andclamp being mounted on the shuttlcfeeler, the member 4 being common toboth parter and clamp and constituting a bladcaw. When. the partcr andclamp are in po- 'sition to act upon the lilling-t bread, as will be thecase when thc lay has completed its forl ward movement, then thefilling-thread will l enter the fceler-notch l and the notch 8 of l thestationary clamp-jaw 7, the bladc-ja'w l and jaw 13 then being open.'lhercaftcr l when the members 4 and 13 are closed they lirst act uponthe thread i, Fig. 5, pressing it down over the lower edge 0 of thenotch 2s and at each side of the jaw T, clamping it tightly between thefaces thereof and the adjacent faces of members 4 and 13%, and as thesaid members continue to descend aftcr the thread has been so clampedits edge 5 will cooperate with the lixed cutting-bhule 2, part ing thethread.

In Fig. 5 the thread t is shown as clamped and also severed or parted.By the doubleacting clamp thus described the thread is held tightly withabsolute certainty, with no opportunity for it to slip or draw throughthe clamping members, insuring its movement into the field of action ofthe thread-cutting temple T, Fig. 2,when the feeler Y returns to normalposition.

The setting or opening of the parting and clamping devices is ell'ectedby cot'iperation of the pin 16 Witha part of the-threatl-cntchersubstantially as in the patent to which I have previously referred, andas such operation is fully described therein it needs no explanationherein.

When the clamp and parter are bodily moved into operative position, theblade-jaw 4 and jaw 13 are open and the heel 6 is in the path of aportion of the lay to be struck as the lay completes its forward beat tothereby rock the blade-jaw and jaw 13 on their t'ulcrum 3 from therelative position shown in Fig. 1 to that shown in Fig. 4, successivelyclam wing and parting the thread 1 adjacent the shuttle.

The lay is shown in Fig. l as cut away (see dotted lines) to leave ashoulder 17 in the path of and to act upon the heel 6 to close themovable members of the parter and clamp at the proper time.

As the return movement of the shuttlefeeler Y takes place the parted andstill clamped thread is brought into engagement with the thread-catcherC before the clamp is opened, so that when the temple thrcanl-cutteroperates to part the thread adjacent the cloth the severed piece ofthread will be held by the thread-catcher in a wclll nown manner.

Rocking of the shaft d in the direction of arrow 50, Fig. 1, positionsthe dog m in the path of the hunter and also permits the operativepositioning of the shuttle-fcclcr, so

that. if the shuttle is properly boxed the ihrcad-partcr andthread-clamp will be positioned to act upon the thread, as has been described.

It the shuttle is improperly boxed, the lcclcr will not move far enoughto bring the parter and clamp into operative position, and as thetilling-rcplcnishing mechanism will not operate at such time thedescribed operation of the thread clamp and parter will not beefl'ccted.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is I a In an automatic filling-replenishingloom, a thread-parter and a thread-clamp, each comprising a movable anda relatively fixed member, to act upon the thread of the filling-supplyto be abandoned, the fixed member of the clamp cooperating with both .10movable members to securely clamp the thread, and means to actuate themovable members to successively clamp and part the thread uponreplenishment of filling.

2. In an automatic filling-replenishing loom, a thread-parter and athread-clamp, each comprising a movable and a relatively fixed member,to act upon the thread of the filling-supply to be abandoned, the fixedmember of the clamp cooperating with both movable members to securelyclamp the thread, a connection between the movable members, and meansacting through such connection to operate the movable members in unisonto successively clamp and part the 2 5 thread uponfilling-replenishment.

3. In an automatic filling -'repi':nishing loom, a threadparter and athread-clamp, each comprising a movable and a relatively fixed member,bodily movable upon replen- -3o ishment of filling into position to actupon the thread of the filling-supply to be abandoned, the fixed memberof the clamp being interj posed between the said two movable'mem-' bersand cooperating therewith to clamp the 5 thread, and means to actuatethe movable members in unison to clamp and partthe thread uponreplenishment of filling.

4. In an automatic filling-replenishing loom, a thread-parter and athread-clamp,
